Abstract
Description
Technical Field
[0001] The utility model relates to the field of thermal pipe supports, in particular to a support structure for installing thermal pipes. Background Art
[0002] In a thermal pipeline system, the design and construction of supports are key factors to ensure the stability and safety of the pipelines. Traditional thermal pipeline supports usually adopt the method of in-situ casting, which requires a large amount of labor and construction equipment, and operations such as drilling and formwork erection are carried out.
[0003] In addition, due to the prominent phenomenon of thermal expansion and contraction of thermal pipelines and the large variety of support systems, the in-situ casting method must wait until the thermal pipeline route is determined before the height, position and type of the support structure can be designed, and then parts can be processed and on-site construction can be carried out. This linear mode makes the construction must be carried out strictly in sequence, not only with low construction efficiency, but also with a greatly increased probability of errors due to the staggered arrangement of various supports along the construction line. Summary of the Utility Model

Specific implementation mode
[0026] Such as Figures 1-5 In [reference], a bracket structure for installing a heat pipe includes a cast-in-place concrete pile 1 and a precast column 2. The upper end of the precast column 2 is provided with a connecting cushion plate 3, and a pipe support seat 4 is arranged on the connecting cushion plate 3. The pipe support seat 4 is provided with a hoop frame 6 for clamping the heat pipe 7. A reserved hole 9 is arranged in the center of the precast column 2. The upper end of the cast-in-place concrete pile 1 is provided with an inserting rod device 8, and the inserting rod device 8 is inserted into the reserved hole 9. A cast-in-place layer 10 is arranged on the outer side of the inserting rod device 8 in the reserved hole 9. There is a cast-in-place section 5 between the cast-in-place concrete pile 1 and the precast column 2, and the cast-in-place section 5 is integrally connected with the cast-in-place layer 10.
[0027] Both ends of the reserved hole 9 are through. The lower end is used for inserting the inserting rod device 8, and the upper end of the inserting rod device 8 is close to the top of the reserved hole 9. Due to the gap left, the precast column 2 can horizontally move relative to the cast-in-place concrete pile 1 to adjust the position, reducing the installation difficulty of the heat pipe. The upper end of the reserved hole 9 can be filled with concrete to form a cast-in-place section 5 between the cast-in-place concrete pile 1 and the precast column 2, connecting the lower end of the precast column 2 with the cast-in-place concrete pile 1, and forming a cast-in-place layer 10 on the outer side of the inserting rod device 8 to connect with the inner wall of the precast column 2.
[0028] A number of concrete cast-in-place piles 1 can be pre-constructed along the route according to the direction of the heat pipe 7. The inserting rod device 8 is embedded in the concrete cast-in-place pile 1. While constructing the concrete cast-in-place pile 1, the precast column 2 is prefabricated in the factory, which helps to save the construction period.
[0029] The connecting cushion plate 3 is bolted to the precast column 2. If the elevation still needs to be lowered after the first pouring is completed, the connecting cushion plate 3 with a thinner specification can be replaced. The installation type of the pipe support seat 4 can be determined according to the actual needs on site. For example, fixing the pipe support seat 4 to the connecting cushion plate 3 with screws is a fixed support. Without installing screws, the pipe support seat 4 can lean against the connecting cushion plate 3 and move freely, which is a translation support. Welding a clamping groove on the connecting cushion plate 3 to limit the pipe support seat 4 to move only along the length direction of the heat pipe is a sliding support.
[0030] In a preferred solution, a demarcation piece 105 is provided at the upper end of the concrete cast-in-place pile 1, and a bottom precast member 201 is provided at the lower end of the precast column 2. A first through hole 204 communicating with the reserved hole 9 is provided in the center of the bottom precast member 201. A plurality of first screw holes 203 are provided outside the first through hole 204 on the bottom precast member 201. A jacking screw 205 is threadedly connected in the first screw hole 203, and the lower end of the jacking screw 205 abuts against the demarcation piece 105.
[0031] The jacking screw 205 is an external screw with a wrench-screwing hexagonal part in the center. Four can be circumferentially evenly distributed. Rotating the hexagonal part adjusts the protruding length of the jacking screw 205 relative to the bottom precast member 201 to adjust the levelness and overall height of the upper end of the precast column 2.
[0032] In a preferred solution, the concrete cast-in-place pile 1 includes a steel reinforcement cage 101 and a concrete cladding 102. An embedded lower section 801 is provided in the center of the concrete cladding 102. The upper end of the embedded lower section 801 is inserted into the reserved hole 9. A plurality of clamping plates 103 are provided on the outer wall of the embedded lower section 801 along the circumference. A clamping groove part 104 is provided at the end of the clamping plate 103. The clamping groove part 104 clamps the upper end of the steel reinforcement cage 101. The demarcation piece 105 is provided above the clamping plate 103. There is a gap between the clamping plate 103 and the demarcation piece 105. A detachable outer formwork sleeve 501 is provided at the cast-in-place section 5.
[0033] The concrete pile head at the upper end of the concrete cast-in-place pile 1 is pre-chiseled. Since the area of the demarcation piece 105 accounts for a relatively large proportion, the height of the demarcation piece 105 is the weak link of the pile head. When breaking the pile head, the edge concrete will break more integrally from this height and expose the demarcation piece 105, which not only reduces the difficulty of breaking the pile head but also makes the broken end surface flat, facilitating the abutment of the jacking screw 205.
[0034] The upper end of the outer formwork sleeve 501 is installed on the side of the bottom precast member 201 through screws. The lower end of the outer formwork sleeve 501 abuts against the height of the demarcation piece 105 and is sealed at the joint. The concrete in the reserved hole 9 flows down from the first through hole 204 and then wraps the metal framework structures such as the demarcation piece 105, the embedded lower section 801, and the jacking screw 205 here. Subsequently, it solidifies into the cast-in-place section 5, connecting the precast column 2 and the concrete cast-in-place pile 1 integrally.
[0035] In a preferred solution, the upper end of the embedded lower section 801 is provided with a cast-in-place upper section 802 connected by threads. The cast-in-place upper section 802 is provided with a plurality of cross bar parts 803 along the circumferential direction. The cast-in-place upper section 802 is inserted into the reserved hole 9, and the embedded lower section 801 and the cast-in-place upper section 802 form an inserting rod device 8.
[0036] Since the embedded lower section 801 was originally a part of the concrete cast-in-place pile 1, the reserved height cannot be too high. Therefore, the exposed part length after the pile head is broken is short, that is, the length of the embedded lower section 801 inserted into the reserved hole 9 is short, and it cannot play a good role in connecting with the precast column 2. In addition, the total heights of the brackets at different positions are not necessarily the same. In order to ensure the unified construction height of the concrete cast-in-place pile 1, it is necessary to precast cast-in-place upper sections 802 with different lengths according to the specific elevation to be butt-jointed with the embedded lower section 801. Therefore, the inserting rod device 8 is designed as the embedded lower section 801 embedded in the concrete cast-in-place pile 1 and the cast-in-place upper section 802 customized by the subsequent factory according to the on-site elevation. The cast-in-place upper section 802 can be provided with a plurality of cross bar parts 803 along the height direction. The cross bar parts 803 can adopt screws. Threaded holes are pre-processed radially on the cast-in-place upper section 802, and the cross bar parts 803 are installed into the threaded holes and exposed at both ends to improve the connection performance with the cast-in-place layer 10.
[0037] In a preferred solution, a second through hole 210 is provided in the center of the top precast member 202. A plurality of first mounting hole positions 208 are provided outside the second through hole 210 on the top precast member 202. An extension sleeve 206 is provided on one side of the bottom precast member 201 and the top precast member 202, and a cross link 207 is connected between adjacent extension sleeves 206.
[0038] The first mounting hole positions 208 are drilled from the end faces of the bottom precast member 201 and the top precast member 202 into the extension sleeve 206 and tapped to form threaded holes for installing the pipe support seat 4. A steel reinforcement cage is also buried inside the precast column 2 during precasting. The extension sleeve 206 and the cross link 207 can be pre-bound or welded with the steel reinforcement cage of the precast column 2. The extension sleeve 206 and the cross link 207 increase the contact area with the concrete of the precast column 2, and the connection of the end precast members after the precast column 2 is formed is more reliable.
[0039] The top precast member 202 is also provided with second mounting hole positions 209 for other installation methods.
[0040] In a preferred embodiment, the pipe support base 4 includes a base plate 401. A fourth through hole 402 is provided at the center of the base plate 401. A third through hole 301 is provided at the center of the connecting cushion plate 3. The fourth through hole 402, the third through hole 301 and the reserved hole 9 are aligned. First half-ring parts 601 are respectively provided at both ends of the base plate 401. Second half-ring parts 602 which are held together are provided on each of the first half-ring parts 601. The first half-ring parts 601 and the second half-ring parts 602 form a hoop frame 6.
[0041] The fourth through hole 402 serves as an inlet for cast-in-place concrete.
[0042] Butt joints are provided at both ends of the first half-ring parts 601 and the second half-ring parts 602 and they are installed by screws.
[0043] The above embodiments are only the preferred technical solutions of the present invention and should not be regarded as limitations on the present invention. The protection scope of the present invention should be the technical solutions recorded in the claims, including equivalent replacement solutions of the technical features in the technical solutions recorded in the claims. That is, equivalent replacement improvements within this scope are also within the protection scope of the present invention.
